PLEASE PREPARE FOR NEXT WEEKS EVALUATION

Please prepare for next weeks evaluation by:

1. Reading the textbook. You should have read the entire unit by now including section 4 which was assigned for homework earlier this week
2. Complete all practice material: Ionic and Molecular naming/formula practice booklet, periodic table practice, and the previously completed ionic/molecular practice assignment
3. Re-read your section 2 quiz and practice with a friend (the tricky fill in the blank quiz)
4. Ensure you have practiced the questions assigned on page 149, 153 and 154 (specific questions to practice are listed on your naming cheat sheet)
5. Complete questions 1-26 on page 176-177
6. Visit: www.edquest.ca and practice the quizzes/tests for matter and chemical change

GET READY FOR ANOTHER BLIZZARD!

IMPORTANT ANNOUNCMENTS:

• MATTER AND CHEMICAL CHANGE UNIT TEST: Monday, March 2nd for 9H and Tuesday March 3rd for 9E and 9B

This week in Science:

• Continuing to learn about ionic and molecular compounds


• Learn more about chemical reactions by learning specifically about how sodium and chlorine form sodium chloride


• Learn strategies for writing formulas for ionic compounds


• Develop skills necessary to write the chemical names of ionic and molecular compounds using the formula


• Finish reading our Unit - if not done in class this week, please read section 4 of your Unit; this is assigned for home reading


• Begin preparation for your Unit evaluation (unit test) next week

FEBRUARY 2009

Hello grade nines! I hope you are all recharged after your time off. We are rapidly progressing through our unit, "Matter and Chemical Change"; be prepared to work hard in the next month (and for the rest of the year for that matter)!

Where are we in the textbook?

• You should have read all of section 1 and 2 and up to page 149 in section 3

What work should I have done?

• Finished check and reflect questions (1-4) on page 143 and page 149 (1-8)

I look forward to learning more about chemistry after the short break!

-Mr. Mang

This week in Science...

* We have now read to the end of section 2 of the unit Matter and Chemical Change; that means you should have read right up to page 134 in your textbook! You also have some homework due for next class!

• All matter in the universe is either a pure substance or a mixture (see picture)

HOMEWORK DUE: Complete the check and reflect questions (1-8 only) on page 134

Due: Wednesday for 9E and 9B and next Tuesday, Feb 3 for 9H

Remember: James Fowler tour is Thursday, January 29 and Friday you are off because teachers have a professional development day

WELCOME BACK!

I hope that everyone had a replenishing holiday! I am excited to teach you in the new year. Please tell me about your holiday some time, I would love to hear about it! We are of course studying "Matter and Chemical Change" at the moment and we will be studying this right into February. Be sure to keep up with the work, as this unit will challenge you! We will begin our studies after the break by examining how avalanches are caused by the unique, and diverse physical properties of water (frozen water); If you would like to learn more about avalanches, please visit: http://www.avalanche.ca/ for online courses, bulletins and more!

• You should have read the first section of the Unit (page 90-109)
• Completed check and reflect on page 96
• Define the key terms and complete check and reflects on page 104 and 109 - see key terms below

HOMEWORK FOR MONDAY (9e/9b) AND TUESDAY (9h)

• Define the key terms: matter, states of matter, melting, freezing, evaporation, condensation, sublimation, deposition, physical poperties of matter, melting point, boiling point, hardness, mallebility, ductility, crystal shape, solubility, density, conductivity
• Complete all check and reflect questions for the section (pg. 96, 104, and 109)

* This work will be due for a homework check next week

* You will have a quiz on the definitions next week...study them!

BUNDLE UP! IT IS ALMOST WINTER!

That's right...it is not officially winter yet despite the frigid temperatures!

THIS WEEK IN GRADE 9 SCIENCE:

• Received our test scores from Space Unit
• Began reading "Matter and Chemical Change"
• Learned about the Physical and Chemical properties of matter
• Explored freezing point of various liquids (coffee, cola, hot water, salt water, regular water)
• Watched a video about the Properties of Matter
• Acted a short skit depicting different phases of matter: solid, liquid and gas
• Discovered that there are different types of mixtures

HAVE A FANTASTIC BREAK! READ AHEAD IN YOUR TEXTBOOK IF YOU WANT EXTRA PREPARATION FOR MATTER AND CHEMICAL CHANGE!

UNIT TEST NEXT WEEK

This is a picture of the meteorite that fell to Earth last week. Scientists found pieces of the meteorite on Thursday in Saskatchewan. A scientist in the USA is offering 10,000 dollars to anyone who recovers a piece!

REMINDER: FORMS AND MONEY FOR JAMES FOWLER TOUR ARE OVERDUE!


November 28:

• We watched a video on Black Holes
• Triangulated a mystery distance; this is the same technique used in conjunction with parallax that astronomers use to calculate the distance to stars!
• Began preparation for our Unit Test next week!

Tips for studying:

• visit: http://www.edquest.ca and use the notes on each section, practice the tests/quizzes for each question
• Re-read the textbook
• Test each other
• Answer the questions in the Unit review at the end of the Unit
• Take next weeks practice tests very seriously!
